Polaroid?

I booked time in the studio to practice with my new (old) Pentax 645N II film camera. I didn’t really have anything important in mind to shoot but I wanted to get time playing with the lights and learning to use the camera. In order to test the exposures I was metering for, before shooting with the expensive film I shot with my digital camera, set to the same ISO, shutter speed, aperture and equivalent focal length. In olden times, a studio photographer might have shot a polaroid in the same way.
